Havre Beneath the Streets in nationwide contest

Havre Beneath the Street is one of 20 finalists for the honor of being USA Today's Best Underground Attraction.

People are asked to vote for their favorite attraction at http://www.10best.com/awards/travel.

People can vote once a day for the duration of the contest.

Voting started Monday and continues through Monday, April 11, at 10 a.m. MDT.

The contest is one of a series in USA Today's 10 Best Readers Choice series in which readers of the nationwide newspaper cast votes for their favorite including the best beer festival, the best sit-down dinner at an airport, best ski town, best geological formation and numerous others.

Havre Beneath the Street is the city's most popular tourist attraction. It portrays Havre after the massive fire of the early 20th century, when, legend has it, businesses of all sorts, from pharmacies to candy stores to brothels, were moved underground.

In the USA Today contest, Havre Beneath the Streets is pitted against 19 other attractions.
